COLLAPSIBLE BABY-CARRIAGE.

1 all whom it may concern:

Be it known that I, ALEXANDER STEIN, a

sub'ect of the German Emperor, residing at Ber 'n, Germany, 63' Weidenweg, have invented certain new and useful Improvements in Collapsible Baby-Carrie. es and other Vehicles; and I do hereby dedlare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame. g

My invention relates to collapsible vehicles, such as perambulators, baby-carria es, childrens wail-carts, and the like, whet er with two or four wheels.

In the accompanying drawings the invention is shown applied to afour-wheeled perambulator.

Figure 1 is a side elevation, Fig. 2 a front view, and Fig. 3 an under side view, of the vehicle in ordinary condition. I Fi 4 shows the vehicle in course of being folds up. Fig. 5 shows the same after folding up. Fig. 6 shows a portion of the vehicle drawn to an enlarged scale for the purpose of better illustrating the method of; folding the Wheels. Fig. 7 is a side elevation of Fig. 6. Fig. 8 is an under side view of a portion of one of the fillets with stays and spring connected thereto. Fig. 9 is a detail view showing the method of connecting the stays with the fillet.

The body of the vehicle consists of a bottom divided into three parts 1 2 3, Fig. 3, hinged together at 4, of the side walls comprising the two parts 5 6, of the front 8, and of the back 7. All these parts 5 6 7 8 are hinged or jointed to the parts 2 3, but not to the part 1, and they may be secured together when the vehicle is in use by hooks and eyes or like catches.

12 and 13 are springs for the axle-pins 1 of the wheels 9 9 1O They are secured, with capability of turnin to the bottom parts 2 3 by means of cranied axes 18, Figs. 6 and 7. Stays 16 17 are suitably jointed to the cranks 2O 21 of the said axes 18, the crank 20 trending upward and the crank 21 downward.

The essential feature of the invention is that the stays 16 17 are formed so as to resent bifurcating resilient arms provide at their ends with lateral members or projections 22, Figs. 8 and 9, whichwhen the springs 12 13 are swung out slide in the guide-grooves 23, formed in the fillets 24, secured to the parts 2 3. At the left-hand side of the vehicle Specification of Letters Patent. Application filed ma 10, 1908. Serial No. 259.707.

thewheels fold up close against the carriagebottom, while on he right-hand side the wheels when folde lie below the left-hand wheels. In this manner when the wheels 9 10 are flapped over upon the springs 12 they lie directly upon the base parts 2 3, while the Wheels 9 10 cover them. In consequence of the crank parts 20 21 trending in opposite directions-viz., in upward and downward directions, respectivelyon the springs 12 and 13, carrying the wheels 9 10, swin ing outward into the position for use, the en portions 22 of the resilient arms 17 slide in the grooves 23 from the inside outward, while on the wheels 9 I 10 being brought into position for use the guide-pins 22 of the stays 16 slide in the grooves 25 from the outside inwardthat is to say, in the reverse direction. 1 For the-purpose of holding the wheels 9 9. 10 10 and the various stays in the position of use, Figs. 6 and 7, and thus maintaining the springs 12 13 in vertical position, the guidegrooves 23 25 are so formed at the ends 26,. which receive the stays in the vertical position of the springs 12 13, Fig. 3 as to present shoulders 28, serving as to receive the stays. When the. baby-carriage is to be collapsed for transit, the catches which hold the walls 5 6 7 8 in position must be releasedand the walls flapped back upon the parts 2 3, Fig. 4. The cover and handle must be removed and the ends 22 of the stays 16 17 pressed together, so that they are released from the shoulders 28, the arms of the stays then entering the narrower portion 27 of the groove 23 immediately the springs 12 13 and wheels lie against the bottom parts 2 3. The parts areheld together in collapsed condition by the ends 22 of the stays 16 17 entering the broader part of the guide-groove at the opposite end. The two bottom parts 2 3, with the side walls and wheels flapped back against them, Fi 4, must then be turned on the part 1 .in sue manner that the Wheels lie one against the other and are completely covered,
